Description Jure Repinc 2006-02-04 16:58:23 UTC

Because fonts were very small I checked what display resolution was. It was set to 1024x768 which is correct. What is not correct is the physical display size. Detected was 347x260 mm. The correct value that other distributions detect for this laptop is 304 x 228 mm.

Configuration issue.

Comment 3 Marcus Schaefer 2006-02-07 10:04:15 UTC

If you don't mind send me the information from

   hwinfo --monitor 

and
  
   /usr/sbin/sysp -q xstuff

Comment 5 Marcus Schaefer 2006-02-08 09:32:27 UTC

Thanks for this information. The bug has been fixed and is available
in beta4. The problem here was that the DDC record is incomplete and sax
doesn't allow reading incomplete data. The fix added a special case to
at least trust the DisplaSize values if there are any

Comment 6 Jure Repinc 2006-03-04 22:30:53 UTC

I just installed beta 6 and physical display size is not correctly detected.
Xorg reports 299 x 241 mm and during installation the summary said that the aspect ration is 5:4 while it should be 347x260 mm and 4:3. Again here is the data that I sent before, because it is different now in beta 6:

Comment 7 Marcus Schaefer 2006-03-06 14:12:50 UTC

Sorry but the DDC record from your monitor said:

 Size: 304x228 mm  ~ 30 x 23 cm

That's ok. If your monitor is at 347x260 mm it simply lies in the
DDC record :-) you can blame the monitor vendor on this but I would
first suggest to meassure the geometry manually

Thanks

Comment 8 Marcus Schaefer 2006-03-08 16:39:41 UTC

I think this is a works for me

Comment 9 Jure Repinc 2006-03-10 10:08:57 UTC

I don't understand why this is happening only with SUSE 10.1 betas. I tried many other distros Like Gentoo, Mandriva and Pingo on this laptop and all of them got the size and correctly.

Comment 10 Jure Repinc 2006-03-11 11:20:55 UTC

Sorry about the confusion in the last comment. The right display size is as reported 304 x 228 mm - 4:3 as detected. But SUSE still set this wrongly at 299 x 241  mm - 5:4 in SUSE 10.1 beta 6. Sorry again.
